Four typical examples of 
perfect healing 
Showing how Nature 
unfailingly responds to 
the scientific methods 
of Davey Tree Surgeons 
]VrATL'RE responds 
-'•^ to the Tree Stir- 
geon"s art by healing- 
over the filling — // the 
ivork has been properly 
done. The rapidity of 
the healing depends on 
the size of the cavity 
and the vitality of the 
tree. Illustrated here 
are four typical exam- 
ples of perfect healing j 
following Davey Tree 
Surgery. They are mereh' repre- 
sentative of the many thousands of 
successful cases handled by the 
1 )avey organization in the past gen- 
eration. 
Photograph Xo. 1 shows a tree at 
the Christian Herald Children's 
I fome, Xyack, X. Y. This tree had a 
splitting and badly decayed crotch, 
requiring a filling from the toj) of 
the crotch almost down tn the 
ground. Note how the bark has 
completely healed over the filling in 
about four years. 
Photograph No. 2 was taken on 
the estate of John D. Archbold. Tar- 
rytown, N. Y., and shows a tree 
with a filling in the side of the 
trunk, .\lmost healed over in about 
six years. 
Photograph X'^o. 3 illustrates a 
tree on the estate of the late Tubus 
French, \\ickliffe. ( )hio. Filling at 
the base of the trunk ivith about five 
_\ears" healing. 
Photograph Xo. -I — .\ tree at 
Kent. r)hio, treated liy the students 
(.)f the Davey Institute, class of 
l''I3. Showing about two years' 
healing : Countersunk boltheads 
completely healed over. Filling in 
the crotch and on one limb partly 
healed over. 
To be perfect. Tree Surgery must 
embody the three following princi- 
ples : All decay must be removed 
and further decay prevented. The 
ca\ity must be so prepared that the 
filling will remain permanently in 
place. All foreign matter must be 
excluded, especially water. It is 
difficult to say which is most impor- 
tant. They are inter-dependent. If 
the operator fails in one he fails 
entirely. these prin- 
ciples e m body both 
science and mechanics. 
A Tree Surgeon must 
be trained in mind and 
in hand. He must have 
both knowledge and 
skill. .\ man who has 
only theoretical knowl- 
edge fails miserably. 
.\n unscientific ope- 
rator works without 
understanding.
